  <p>Edit the above to make any music you like. <a href="https://github.com/fulldecent/system-bus-radio/issues/28">Tune file format</a> is time (ms) and frequency (Hz).</p>
  <p>Chrome has errors if you open this file locally (<code>file://</code>). Try using <code>php -S localhost:8000</code> or similar for a quick web server.</p>
